Description

The STTH1502 uses ST's new 200V planar Pt
doping technology, and is specially suited for
switching mode base drive and transistor circuits.
Packaged in TO-220AC, TO-220FPAC, and
TO-220 Ins, this device is intended for use in low
voltage, high frequency inverters, free wheeling
and polarity protection.
